Add vm.expect* and vm.assume cheatcodes

Given the popularity of the vm.expect* and vm.assume cheatcodes in foundry, we should also support the following:
1. `vm.expectRevert`
2. `vm.expectEmit`
3. `vm.expectCall`
4. `vm.assume`

The core technical requirement of this issue is to ensure that the functionality of these cheatcodes works _exactly_ as they do in foundry.
